A significant improvement to epi-thermal neutron, position-sensitive detectors, is proposed.  The device addresses existing deficiencies in spatial resolution, continuous 2-D shaping, detection efficiency, and large area coverage.  In particular, the detector has a very fast response times for time-of-flight experiments.  Multichannel plate technology that has been effectively used for UV and charged particle detection is being optimized for neutron imaging and energy determinations.  The final goal is to produce a large area (~ 1m²) detector with good spatial resolution and fast (microsecond) timing resolution.  In Phase I, a small prototype device of optimal composition glass will be constructed.  The unit will have a small radius of curvature.  This unit will be tested on a neutron beam line for time constants, spatial resolution, and energy response.
